Installing Your Shock

WARNING: Rear shock setup and configuration varies greatly between different bicycle manufacturers. Be sure to refer to the owner's manual for your bicycle. FOX products should be installed by a qualified bicycle service technician, in accordance with FOX installation specifications. Improperly installed shocks can fail, causing the rider to lose control, resulting in SERIOUS INJURY OR DEATH.

Check for clearance before riding.

If you are installing your shock on a bike for which the shock was not original equipment, follow the steps below to ensure proper clearance before riding.


  1. Remove the coil spring from your shock.
  2. Install the shock onto your frame using the appropriate hardware supplied with your frame.
  3. Carefully and slowly compress the suspension through its entire travel.
  4. Check that no part of your shock contacts any portion of your frame or linkage as it cycles through its travel.
  5. Remove the shock from your frame, reinstall the coil spring, and reinstall your shock. Check that the spring does not contact any portion of your frame or linkage.
  6. Set sag as described in the "Setting Coil Spring Preload" section below.

Before You Ride

Make sure that your shock is ready to ride

  1. Clean the outside of your shock with mild soap and water and wipe dry with a soft rag.
    • Do not use any solvents or de-greasers as these products can damage the shock's exterior finish.
    • Do not use a high pressure washer or spray water directly at the seal/shock body junction.
  2. Inspect the exterior of your shock. The shock should not be used if any of the exterior parts appear to be damaged
    • Contact your local FOX dealer or FOX directly for further inspection or repair.
  3. Make sure that your quick-release levers (or thru-axles) are properly adjusted and tightened.
  4. Check your headset adjustment. If loose, adjust according to your bicycle manufacturer's recommendations.
  5. Check that all brake cables or hoses are properly fastened.
  6. Test the proper operation of your front and rear brakes on level ground.

Setting Coil Spring Preload

Sag should be set to ~30% of total shock travel

  1. Measure the eye-to-eye distance of your bike's shock mounts.DHX2-sag-range.jpg
  2. With the help of a friend, mount the bike in your normal riding position with your normal riding gear and measure eye-to-eye distance again.
  3. The difference between the two measurements is sag.
    • To increase sag, turn the preload adjuster counter-clockwise. If you cannot achieve 30% sag by turning the preload adjuster, you will need to obtain a lower rate spring.
    • To decrease sag, turn the preload adjuster clockwise no more than two full turns. If you cannot achieve 30% sag by turning the preload adjuster, you will need to obtain a higher rate spring.
    • To change to a higher or lower rate spring, see the Changing Coil Springs section below.



Suggested Sag Measurements
Travel 30% Sag
51mm/ 2.00in 15mm/ 0.60in
57mm/ 2.25in 17mm/ 0.68in
63mm/ 2.50in 19mm/ 0.75in
76mm/ 3.00in 23mm/ 0.90in
89mm/ 3.50in 25mm/ 1.00in

Changing Coil Springs

If necessary, changing coils can help you achieve proper sag.

  1. Loosen the preload adjuster until the spring freely moves.
  2. Lift up the coil spring and remove the slotted spring retainer and the spring retainer insert (spring retainer insert only found on Factory and Performance Elite Series shocks, no spring retainer insert is used on Performance Series shocks).
  3. Slide the coil spring off the shock body. Depending on your bike model, you may need to remove the shaft eyelet hardware to create enough clearance to remove the coil spring. Information on eyelet hardware can be found at SHOCK- Eyelet Hardware Maintenance » 
  4. Slide the new coil spring onto the shock body.
  5. Install the spring retainer insert back on the shock with it's protruding section going into the inside of the coil spring (Factory and Performance Elite Series only).
  6. Install the slotted spring retainer with it's recessed side toward the shaft eyelet and it's protruding section inset within the spring retainer insert or coil spring on Performance Series shocks.
  7. Tighten the preload adjuster just until the spring no longer moves.
  8. Turn the preload adjuster one additional full turn.
  9. Recheck sag as detailed in the Setting Coil Spring Preload section above.


Recommended Starting Damper Settings (Factory and Performance Elite Series)

Use the information about your specific bike and shock combination in the table below to help determine which table of recommended dampers settings to try.












Determine which table to use (A, B, or C) depending on your result from the table above. Spring rate is printed on the spring of your shock. Use your spring rate value in the correct table below to find the suggested starting damping settings for your shock. Factory Series shocks will utilize all recommended damping adjustments (HSC, LSC, HSR, and LSR). Performance Elite Series shocks will only utilize the recommended LSC and LSR adjustments.


Turn all damper adjusters to the closed position (fully clockwise) until they stop. Then back them out (counter-clockwise) to the number of clicks shown in the appropriate table below.

Adjusting Rebound

Rebound controls how fast the shock extends after compressing

The rebound adjustment is dependent on the coil spring rate. For example, higher coil spring rates require more rebound damping.


*High-speed Rebound (HSR) adjustment is useful to allow the shock to recover from bigger hits and square-edged bumps quickly enough to absorb consecutive hits. Turning the 6mm Hex clockwise (in) slows down High-speed rebound, turning the 6mm Hex counter-clockwise (out) speeds up High-speed rebound.

Low-speed Rebound (LSR) adjustment is useful to control shock performance during brake bumps, technical climbing, and offcamber cornering, when extra traction is needed. Turning the 3mm Hex clockwise (in) slows down Low-speed rebound, turning the 3mm Hex counter-clockwise (out) speeds up Low-speed rebound.


Adjust rebound until when tested, the shock returns quickly but does not top out.

Top out is felt when a shock fully extends too quickly and comes to an abrupt stop when it reaches full extension (you will hear/feel a small noise). Top out should be avoided through proper rebound setting.



*Factory Series only

Adjusting Compression Damping (Factory and Performance Elite Series)

Adjusting your high and low speed compression setting controls how the shock feels as it's compressed through its travel under various types of hits. Use your high and low speed compression adjusters to tune the fork to meet your riding style and terrain.




*High-speed Compression (HSC) adjustment is useful to control shock performance during bigger hits, landings, and squareedged bumps. Turning the 6mm Hex clockwise (in) adds High-speed compression damping (firmer), turning the 6mm Hex counter-clockwise (out) reduces High-speed compression damping (softer).

Low-speed Compression (LSC) adjustment is useful to control shock performance during rider weight shifts, G-outs, and other slow inputs. Turning the 3mm Hex clockwise (in) adds Low-speed compression damping (firmer), turning the 3mm Hex counter-clockwise (out) reduces Low-speed compression damping (softer).


*Factory Series only


Adjusting Compression Damping (Performance Series)

Turn the blue LSC adjuster clockwise by hand, to increase low-speed compression damping. The LSC adjuster primarily affects the compression damping during slow speed suspension movements, such as pedaling, g-outs or smooth jump landings. It also affects the wheel traction and harshness (or plushness) of your bicycle. The LSC adjuster has ~16-18 clicks of adjustment range.


Service Intervals

To best maintain the performance and durability of your product under normal use, FOX recommends that you have regular fork and shock maintenance performed according to the service intervals listed below.

*For those who ride lift-accessed DH, Park, or Extreme Freeride or in extremely wet/muddy or dry/dusty environmental conditions where trail debris is sprayed onto the fork or shock while on the trail, FOX encourages riders to perform maintenance earlier than recommended above as needed. If you hear, see, or feel something unusual, stop riding immediately and contact a FOX Authorized Service Center for proper servicing.

WARNING: FOX products should be serviced by a qualified bicycle service technician, in accordance with FOX specifications. If you have any doubt whether or not you can properly service your FOX product, then DO NOT attempt it. Improperly serviced products can fail, causing the rider to lose control resulting in SERIOUS INJURY OR DEATH.
